My present invention refers to combination locks, more particularly to combination locks of the type having two regulating or setting movements in the same member, one for operating said member into position relatively tothe separate tumblers and the other for operating the tumblers. Y

The main object of the invention is to provide a lock of the type referred to being operable in an easy and simple manner to those who know the combination of the lock but having so large a number of combination possibilities that the probabilityfor a person, who does not know the combination, to find the correct combination is exceedingly small.

Another object of the invention is to provide a combination lock which will dispense with the use of a key for locking or unlocking, the lock being operable by means of a regulating member permanently arranged in the lock.

A further object of the invention is to provide a simple construction of said regulating member in order that the operation of thelock in putting the correct combination may be easily performed.

Other objects of the invention will appear from the following.

The invention may be applied to locks adapted t0 a plurality of different purposes, as for instance door locks in houses, locks in writing-tables, document boxes, safes and locks in automobiles for doors as well as the ignition or the gear-box. In a simplied form the invention may also be applied to padlocks and locks for bicycles.

In the following description same reference numerals indicate corresponding parts in the various gures. i

The form of construction illustrated in Figs.

1-6, inclusive, comprises a suitable casing I0 Y.,

is adaptedto move longitudinally between guides f stem |6 is secured Vto the cover and the opposite wall ofthe casing I0, said stem passing through a longitudinal slot I1 in the bolt and the slide-plate |4, permitting the longitudinaly movement of the bolt and the slide-plate. Secured to the slide-plate I4 is a projection I8 extending transversely in the casing and passing through a longitudinal slot I9 provided in the bolt I2 in order to enable the bolt to move ndependently of the slide-plate. The bolt and the slide-plate are held in locking position by a spring 20 acting upon the rear end of the bolt. The bolt I2 can be brought out of its locking position by way of the projection |8, when the slideplate is forced against the action of the spring 20. As shown in Figs. 1 and 6 the length of the slot I9 is adapted so as to enable the bolt to move out of its locking position without moving the slide-plate in operating the lock by means of a handle or knob 2| secured to the bolt and adapted to slide along a slot 22 provided in the cover II. The knob 2| is adap-ted to rotateabout a pin 23 secured to the bolt. The portion of the knob 2| extending through the slot 22 is provided with two plane surfaces at opposite sides of the knob so as to enable the knob to be moved along the slot 22 which has a narrow central portion connecting two circular holes 24 and 25 forming part of the slot as will be seen from Fig. 6.V Said arrangement enables the bolt to be stopped when being in its unlocking position by rotating the knob 2| about an angle of 90 in the hole 24, and in a similar manner to be stopped in its locking position by rotating the knob 2| in the hole 25. Since the knob is provided inside the door the lock cannot be opened from the outside in the latter case. v

Rotatably mounted on the stem- |6 are six tumblers 2|;V all having theV same exterior form and the same thickness. At the top edge of each tumbler is secured one end of a spring 21 the other end of which presses against the inner wall of the casing I0 and has a tendency of rotating the tumblers counter-clockwise as seen in Fig. 1. The tumblers 26 are separated from each other by thin spacing members or washers28 carried by the stem I6. The ends of the tumblers are arc-shaped the arcs being concentric to the axis of the stem I6. One end of each tumbler is provided with a series of teeth 29 at theedge and each of said tooth series or racks is engaged by a pawl 3| pressed against the teeth by a spring 33. The pawls 3| are rotatably mounted on a stem 30 and separated in relation to each other by spacing members 32, and each individual pawl 3| is adapted toengage the teeth 29 of the tumbler positioned in the same plane as the pawl,

whereby, said tumblers may be stopped in a plurality of different positions. The number of said `positions is equal to the number of operating positions to which the regulating member can be moved. In the present case said number is ten, and consequently there are ten teeth at each tumbler. l Y

An important part of the present invention is the regulating member by which the tumblers are operated to move to positions in which they allow the bolt to be moved andthe lock to be opened. According to the invention said regulating member'is adapted to be operated manutumbler to the following one to be operated. In the form of construction shown in Figs. 1-6 in elusive the automatic movement of theregulating member is a rectilinear movement, the various tumblers being operated by using a rotational movement of the regulating member. To guide the regulating member, the construction of which will be clear from the following description,there is provided a shaft 35 extending transversely through the casing I0 from the cover to which it isY secured, outside the casing through an opening surrounded byr a flange 36 at the opposite wall thereof. Mounted rotatably and slidably on said shaft 35 is a cam 31 forming part of the regulating' member. Said cam has a tubular hub 38 inserted in and secured to one end of a tube 39 the other end of which being provided with a sleeve 48 inserted therein and guided by the shaft 35. In addition to the cam adapted to engage the tumblers, the regulating member comprises manually operable means to effect its rotational movement. Said means consists of a dial of substantially the type used in automatic telephones.

As shown in Figs. 3 and 5 the dial comprises a circular-plate 4| provided with numerals and fitted at the square outer end of the shaft 35.

A finger stop or abutment 42 `extends radially fromr said plate 4| which is held in position on the shaft 35 by means of a screw 43 extending longitudinally through the hollow shaft and secured to the outer side of the cover by means of a nut 44 provided with suitable key holes 44. Rotatably mounted on the shaft 35 inside the number plate 4| is a plate 45 provided with ten nger holes 46 positioned on a circle concentrically to the axis of the shaft 35.` The rotatable plate 45 is prevented from moving axially on the shaft 35 by a shoulder 41 formed integrally therewith, and by the number plate 4|. integrally with the rotatable plate 45 and surrounds the tube 39. At one side said sleeve 48 is provided with an axial slot 49 in whicha pin 59.screwed in the tube 39 and the sleeve 4|J and extending radially outwards therefrom, is adapted to move axially. In the tubular space between the shaft 35 and the tube 39, a helical spring 5| is positioned, one end of which spring is secured to the shaft 35, the other end being fixed to the tube 39 in such a manner as to tend to turn the tube 39 counter-clockwise and at the same time to force it axially towards the cover As would have been clear from the above the regulating member comprises substantially two parts which are movable axially in relation to each other, i. e. the cam 31 and the dial for its operation. The tube 3 9 transferring the rotational movement from the dial to the cam may be considered as integral with the cam and may also be constructed in agreement herewith without A centrally extending sleeve 48 is provided departing from the function intended for the cam. As will be described below the dial may also be provided to move axially together with the cam. The cam has a helical sliding surface or edge adapted to cooperate with an edge of the tumblers, and the length of said sliding surface is such as Vto correspond to all positions of the tumblers, i. e. when the cam has been'V rotated through an angle corresponding tothe total length of the sliding surface, the tumbler engaging the sliding surface has passed through all its positions defined by the teeth 29 and the pawl 3|.

In order to arrest the regulating member in effective position to actuate the individual tumblers I provide an abutting means on said member adapted to cooperate with the tumblers to effect said arresting. In the form of construction shown in Fig. 1 said abutting means comprises a projection 52 extending radially from the hub of the cam 31 and adapted to engage in its arresting position the lowermost corner of the tumbler. The radial abutting surface of said projection is positioned relatively to the sliding edge of the cam soas to retain said edge of the cam in alignment with the tumbler to be operated when the said abutting surface engages the face of the tumbler. The Width of the helical or sliding surface of the cam 31 is suitably somewhat less than the total thickness of one tumbler 26 and one spacing member 28. In order to arrest the cam 31 in its turning movement under the action of the spring 5I and to hold it in an initial or normal position when being in alignment with a tumbler I provide an abutment 53 in the form of a plate bent downwards at its free edge and secured at the other end to the wall of the casing I l) as shown in Fig. 1. The Width of said plate counted in the direction of the axis of the regulating member is equal to the total depth of the tumblers and the washers or spacing members therebetween. However, the cam may be moved some distance beyond the last tumbler towards the cover II, in which position the front of the cam engages the inner side of the bolt and a projection 54 secured to the slide-plate I4 will stop the cam in its rotation movement. 'Ihe cam can also be moved a small distance towards the dial beyond the outermost tumbler at this side of the casing. Into said position, the cam will be withdrawn by means of the pin 59 being moved towards the rear of the finger plate 45 of the dial. The rotational movement of the cam 31 is arrested in said position by a sliding member 55 carried and guided by the stem I6 and by a screw bolt 56 as shown in Fig. 4. Said member 55 is separated from the adjacent tumbler and pawl by a spacing member of the same shape and thickness as those of the washers 28 and 32. Extending at right angles transversely to the sliding member 55 and secured to the top edge thereof is a releasing member for the pawls 3l in the form of a bar 51 positioned in front of the top of the pawls 3i so as to enable all of the pawls to be disengaged from the racks 29 at the ends of the tumblers by moving the sliding member 55 in a direction towards the pawls, so that'the tumblers will return by action of their springs 21 to the initial position shown in Fig. 1 in which position the bottom corners of the tumblers engage the hub of the cam 31. Said corner of each tumbler will nearly touch in said position the portion of the helical surface of the cam positioned next to the centre thereof when the cam is in its initial angular position defined by the abutment 53. When the tumblers are in their initial position, the top surface of the projection I8 is on aV level with their top edges without touching them but is prevented by the turnblers from moving from its locking position. This cannot occur until each individual tumbler is put in such position as to have a radial notch in the edge thereof situated in alignment with the projection I8. Such a notch 58 is shown in Fig. 1 in the tumbler 26 appearing in said figure.

In order to retard the cam 31 in its return after putting the tumbler in position a retarder may be arranged in a suitable manner. For instance, a leaf spring 59 shown in Fig. 1 will do for said purpose. The spring 59 should extend transversely through substantially the entire width of the space in the casing, and is adapted to engage the helical edge of the .cam 31 when said cam has turned through a predetermined angle from its initial position. The pressure of the spring against the cam and thus the retarding action thereof will increase as the cam turns from its initial position.

The manner of action of the lock according to the embodiment now described is as follows.

The invention also includes means to prevent opening the lock and the door by forcing the outer or engaging portion I3 thereof back, for instance by means of a chisel inserted between the door and the door-post. As shown in Figs. 1 and 2 said means comprises a stopping member 20|] pivoted at 25! on the wall of the casing. The free jend of said member has an upper bevelled surface 253 adapted to be engaged by a transverse bar 234 xed to or integral with the above-mentioned sliding member 55, and a lower bevelled surface `2115 adapted to be engaged by an upstanding projection 205 on the top edge of the slide-plate I4. A leaf spring 2D? secured to the wall of the casing at 208 is adapted to keep the stopping member in a lower position determined by a swell 233 thereon engaging a depression in the stopping member as shown in Fig. 1 or an upper position in which said swell engages a similar depression 2|() in the stopping member. A projection 2H of the member 250 extends downwards to engage a recess 2 I2 in the upper edge of the bolt. In operation the projection 2| I prevents the bolt from being forced back by cooperation with the forward edge of the recess 2I2. In opening by way of the slide-plate I4, the projection 206 engages the bevelled surface 205 of the member 20) forcing said member upwards into a position, in which the projection is above the top edge of the bolt so that the bolt may be moved by proper operation of the lock. The member 230 will be retained in said upper position by the spring 201. If desired to return the member 255 to its stopping position from outside the door, the cam of the regulating member should be set in a position to cooperate with the sliding member 55 as shown in Fig. 4 and turned counter-clockwise as seen in said figure, so that the sliding member 55 will be forced back and the end of the transverse bar 'Z55 will engage the upper bevelled surface 263 of the member 256 forcing it downwards.

Furthermore, the invention includes means tov release the pawls of the tumblers automatically i when the bolt is forced back in shutting the door. Said means may be manually operable from the inner side of the door so that it can be brought out of action in case the lock is to be retained in unlocked position for a long period of time. As shown in Figs. l, 2 and in detail in Fig. 20 said means consists of a dog 2I3-1ixed to a shaft 2l@ rotatably mounted at the top edge of the bolt I2. The shaft 2I4 extends through slots 255 in the slide-plate lli and the wall I I of the casing tumblers.

position all tumblers 26 must at rst be put in a position so as to have their notches in registry mutually and in relation to the projection I8. In Figs. 1, 2 and 3, the tumblers 26 and the cam 31 are shown in their initial position in full lines, the cam being in eiective position in relation to the rst tumbler counted from the dial, and is prevented by the abutment 52 on the hub of the cani from passing said tumbler under the action of the springr 5I. Suppose that the number of the combination is 603,915. In order to operate the tumblers according to said combination the operator has to insert the point of his finger in that hole in the fingerplate of the dial which is positioned at the numeral six on the number plate 4I, the finger plate being turned counter-clockwise until the nger will stop against the abutmentV 42. At the beginning of the rotational movement, the abutment 52 on the hub cf the cam will become free from the bottom edge of the rst tumbler but since the cam has now been turned a certain angle the edge thereof will abut against the second tumbler when the cam is forced axially under the action of the spring 5I. The extent of said axial movement o f the cam is thus relatively small being'equal to the thickness of the spacing member between the rst and the second tumbler. The face of the cam will Vthus engage the second tumbler and slide along the face thereof without turning the tumbler at the further movement of the cam, the pressure of the spring engaging the pawl at the second tumbler being large enough to retain said tumbler in position. As the cam is turning, the helical edgeA thereof will force the rst tumbler against the action of the spring 21 to the position six, in which the notch 58 is in registry with the projection I8. The rst pawl 3| will retain the tumbler in said position. The dial is released by the nger and the cam will return to its initialposition under the action of thev spring 5I. In the initial position the edge of the cam is disengaged from the lower edge of the second tumbler, and the cam will thus move axially until the abutment 52 will be arrested by said tumbler. The operator will now take the numeral 0, whereby the second tumbler will be turned onlyto such an extent as to allow the cam to pass the lowermost corner of said tumbler. The notch 58 of said tumbler is thereby turned to obtain a position in registry with the projection I8 as shown in dotted lines in Fig. 1. It Will be seen that when the cam has obtained its initial angular position, the top surface of the abutment 52 is just able to pass closely below the second tumbler being in its nought position, to proceed to effective position in relation to the third tumbler. The remaining tumblers are operated similarly by taking the numerals 3, 9, 1 and 5 successively on the dial. After setting the last tumbler and returning to its initial angular position, the cam has passed the said tumbler and will rest at its radial edge 31 against the projection 54 of the sliding plate I4. It is now possible to move the bolt I2 out of locking position by using the nger plate 45 as a handle and turning it clockwise,

the radial edge of the cam engaging the projec- Y tion 54 of the sliding plate I4 and forcing it together with the bolt by way of the projection I8 out of locking position. The inwardly directed portion of the projection I8 will slide at this movement into the registering notches of the After opening the door BI the bolt is permitted to return to its initial or locking position under the action of the spring 20, the finger obtained in the sleeve 48 of the rotatable plate,V

45. The radial edge 31 of the cam will now engage the lower corner of the sliding member 55 as shown in Fig. 4 of the drawings. By turning the rotatable plate 45 counter-clockwiseV in Fig. 4 through a small angle the sliding member 55 may now be moved a distance sufliciently 'to release by means of the bar 51 the pawls and theV tumblers which will return by the action of the springs 21 to their initial position shown in dotted lines in Fig. 4. The dial and the pin 50 are now released, the latter being returned by means of the spring 5I to its initial position shown in full lines in Fig. 3. The bolt is now in its locking position again and the door may be shut. At shutting the door the bevelled face of the bolt will be forced back into the casing, this movement being permitted in spite of the tumbler being in locking position because the bolt is free to move independent of the sliding plate I4 and the projections I8 and 54 thereof due to the `slot I9 and the downward extension I9 thereof in the bolt. The manner of opening the lock from inside or outside the door' and of stopping the lock in locking or unlocking positionis already described above.

It will be clear from the above that the lock according to the present invention is of such construction as to avoid any possibility of concluding the correct position of the tumblers by feeling or listening. As a matter of fact the projection I8 does not engage any tumbler when they Vare being put in position, and the projection I8 cannot possibly be forced against the tumbler when being in incorrect position until'all tumblers have moved out of their initial or normal position.

It is to be noted that the combination of the lock is defined by the angular position of the notches on the tumblers. In the form of construction shown in Figs. l-6 inclusive the combination may be changed only by removing the tumblers from the lock and substituting them by others having the notches in other positions. However, it is also Vpossible to provide each notch in a separate part of the tumbler, said part being adapted to be set on the remaining part of the tumbler in a number of positions corresponding to the numerals at the dial. This possibility is illustrated by Way of example in Figs. '1 and 8, in Which a tumbler is divided in two portions 26a and 2Gb adapted to be set in different angular positions in relation to each other. 'Ihe portion 2Gb may thus obtain positions as killustrated in dotted lines in Fig. 8. 'I'he portion 26a'having the notch 58 and the portion 25h having the tooth rack 29 are each provided at the centre with a surface 26e having radial undulations adapted to keep the portions 26a and 2Gb in a definite angular position in relation to each other when compressed in direction of the axis of the stem I6 on which they are mounted loosely. Although only one tumbler is shown in Figs. 7 and 8 it is evident that a plurality of such tumblers may be mounted as shown in Figs. 2 `and 3, for instance, the various tumblers cooperating to retain their portions in correct relation to'each other.

loV

l'n order to save space-and reduce the outer dimensions of the lock the tumblers may be mounted concentrically to the longitudinal axis of the regulating member and the remaining parts of the lock may be modified in regard thereto. An

example of such arrangement of the tumblers is shown in Figs. 9-11 inclusive. According to said 'modication the tumblers 26d have the form of circular disks mounted loosely on the hollow shaft 35d on which the tumbler actuating portion of the regulating member is adapted to move axially as described in connection with the former embodiment of the invention. Instead of a cam for the operation of the tumblers an angular arm 'I0 may be secured to the tube 39d of the regulating member, the free end. of which arm has a radial projection 1I adapted to cooperate with the tumblers to turn them out of their normal or Yinitial positions. In order to realize the axial movement of the regulating member in spite of the fact that the tumblers are mounted on the same shaft 35d as the regulating member, each tumbler disk is provided with an opening 'I2 extending through a substantial arc so that only a small sector 'I3 and a hub portion I4 are left to carry the tumbler disk on the shaft 350D. At a point of the circumference said opening 'I2 forms a radial shoulder I5 adapted to be engaged by the projection II of the angular arm 1.0. A lateral abutment 'I6 formed integrally with the projection 'II overlaps the tumbler adjacent to said shoulder 'I5 so as to arrest the regulating member in effective position in relation to the tumbler. At the arc-shaped periphery each tumbler has a tooth rack 29d engaged by a pawl 3Id forced against said rack by a spring 33d as in the former embodiment of the invention. A spring 21d having one end secured to the tumbler disk at a suitable point and the other end carried by the wall of the casing i tends to turn the disc 26d counter-clockwise in Fig. 9, said movement being limited by a pin I'I extending transversely through the inner end of the casing, and an arcshaped slot I8 in the tumbler adapted to receive said pin 11, said pin may be xed to the wall of the casing. The length of the slot 'I8 corresponds to the length of the tooth rack 29d so that when in turning the disk, all teeth 29d have passed the pawl 3|d, the slot has passed the pin over its whole length. A notch 58 adapted to receive the projection I8 is arranged in correspondence to the embodimentrdescribedin connection with Figs. 1-6 inclusive. However, according to the present embodiment the lock is not adapted to be operable from the inner side of the door so that no slide-plate is needed, the projection I8 being secured directly on the bolt I2. The latter is provided with a large recess 83 to receive the projection II of the regulating member in its effective position to operate the bolt. In said position the projection II engages anedge 84 of said recess being forced thereagainst by the spring of the regulating member. A channel-shaped guiding member I9 shown in section in Fig. 9 and in elevation in Fig. 11 is secured to the wall of the casing opposite to the cover II as shown in detail in Fig. 11. It is to be noted that Fig. l1 shows the channel I9 as seen in direction of the arrow 80 in Fig. 9 and that Fig. 11 is a fragmentary showing of portions of the cover II, the opposite wall of the casing I0 carrying the channel, the bolt I2 and one tumbler 26d adjacent to the bolt. The channel 'I9 is open at both ends, the projection 'II of the angular arm 'I0 being received in the channel after operating all tumblers. 'Ihe projection II enters the channel at the end adjacent to the bolt I2 to be moved in said channel to the opposite end thereof where it may escape through a lateral opening 8l formed by cutting out the left hand ange of the channel at the end thereof, as seen in Fig. 1l. It will be seen that the channel serves as an abutment for the projection 1I when said projection is in its effective position Y outside the channel as will be clear from Fig. 9 in which the angular arm 'IB and its projection 'II tend to turn counter-clockwise under the action of the spring of the regulating member. Said spring may of course be of the same construction as the spring I shown in Fig. 3 and is to be mounted in the tube 39d as shown in said figure.

Instead of a circular dial for operating the regulating member the manually operable part of said member consists of an arc-shaped member 45d connected to the sleeve 48 by a radial arm integral with both said member 45d and the sleeve 48 as shown in dotted lines in Fig. 9 and in full lines in Fig. 10. The arc member 45d has ten shoulders 46d corresponding to the nger holes in the former embodiment and adapted to be engaged by the finger when operating the lock. This arrangement has the advantage as compared with the dial described above that the nger positions or shoulders may be distributed over a relatively small angle that is suitable in the present case since the tumblers must be turned the same angle as the regulating member. The arc-shaped member is adapted to be operated in connection with a fixed linger stop similar to that described above. It is to be noted, however, that the numbers of the various finger positions are provided at the movable member 45d instead of the stationary member 42 of the dial mentioned above.

The pawls Sld engaging the teeth 29d of the tumblers may be released by means of the cross bar Sid of the sliding member 55d. For that purpose the lower edge of the bolt I2 has a shoulder 82 adapted to engage the releasing bar 51d at the end of an unlocking stroke of the bolt, i. e. when the projection I8 is received by the notches in the tumblers.

The operation of the embodiment now described is similar to that of the previous one and need not be described in detail. The regulating member is, in the position shown in full lines in Fig. l0, in its initial position in which the abutment V1S of the projection 1I engages the face of the rst tumbler at the radial shoulder 15, whereby the regulating member is prevented from moving axially under the action of its spring. Inv

taking a certain numeral at the arc-shaped operating member 45d, the projection of the angular arm li] turns the rst tumbler a corresponding Y angle to a position in which the tumbler is retained by the pawl Bld. VWhen the operating member 55d is released, the angular arm will return under the action of the spring of the regulating member, until the projection II engages and is arrested by the lateral flange of the channel-shaped guide 19. In the initial part of said movement the abutment 'I6 will be disengaged from the tumbler at the shoulder 'I5 and will move axially to engage the next tumbler, on which the projection 'II will slide, until it reaches the shoulder 'I5 of the tumbler in question, whereas it is moved axially until it is arrested by the abutment 16. The same process will be repeated at the remaining tumblers. When the last tumbler has been set in position, the projection 'Il of the regulating member slides into the recess 83 in the bolt and will engage the edge 84. supposing that all tumblers have been set in correct position, the lock may be opened by turning the regulating member counter-clockwise, the arm carrying the arc-shaped member 45d serving as a fthe channel 19 Without contacting the tumblers handle. The bolt will then be forced out of lock'- ing position by the projection of the arm 10. When the bolt khas returned, the projection 1| obtains the position shown in Fig. ll in alignment with. the end of the channel-shapedguide 19. By means of the pin the axially movable part of the regulating member, i. e. Ythe arm. 10 and the tube 39will be returned to theirinitial axial position, 'the projection 1| being guided by or the edges of the openings l2. The projection Il will move through the lateral opening 8|. out of the'channel-shaped guide at the end of the axial returning movement and is then set in correct position in relation to the iirst tumbler, i. e. will obtain the position shown in Fig. 9.

Instead yof transmitting the movement of the regulating member to the tumblers by means of acam or an angular arm it may be suitable in certain cases to use a gear transmission to effect said movement. Figs. 12-13, inclusive, show such an arrangement diagrammatically, such portions being included only as are needed for a comprehension of the construction and operation of the gear transmission proper, in that the remaining parts ofl the lock may be constructed as shown in connection with any of the previous embodiments. The .tumblers 26e of which one only is shown are loosely mounted on a stem |6 which is parallel with and arranged laterally of the screw 43e which in analogy with Fig. 3 supports the iixed part of the regulating member, that is to say the abutment or stop for the nger plate.

Instead of a cam-disk, such as shown in Fig. 3,

' the tube 39e is provided at its inner end with a toothed wheel 85 fixed thereto for engagement with racks 86 of the tumblers 26e. Tube 39el is rotatably mounted in a sleeve 86 that has a radial arm 8l' provided with a hole through Whichv extends a screw 88 extending entirely through the lock and being iixed to the walls of the casing of the lock. The supporting member 89 which is removably fixed to the arm 81, extends radially over and above the end surface of the toothed wheel 85. The tube 39e and the toothed Wheel fixed thereto may thus be turned in relation to the sleeve 86 but cannot be moved axially in relation to the latter. One end surface of the toothed rack 86 abuts the end of an arc-shaped part 90 of the tumbler 26e in a manner as shown in Fig. 12. It may be supposed that the tube 39e is actuated in the` same manner as was the case in the embodiment shown in Fig. `3 by means of the spring of the regulating member and therefore it tends to move axially toward theinterior of the lock. In order to obtain a stepwise movemovement imparted to tube 39e by the nger plateris transferred by the Wheel 85 to the rack 86 of the tumbler, so that this latter is rotated a certain angle corresponding to the setting angle of the finger plate, The mode of operation is analogous with what has been described in connection with the precedingl embodiment, and therefore it need not againrbe explained in this connection. It is obvious that a guide for re-` turning the projection 9| in axial direction afterV the setting of all tumblers may be arranged in the same way as shown in connectionwwith the projection 1| in Figs. 9 andrll. l

Instead of carrying out the regulating member in two parts one of which, that is to say the operating part, is stationary in axial direction and the other is displaceable in axial direction for the purpose of setting the same into operative position in relation to the respective tumblers, the regulating member may be executed so as to have its operating part, that is to say the finger plate and the finger stop cooperating therewith, capable of moving axially and of partaking in the movement from one tumbler tothe next.

Such an embodimentv of the regulating member is illustrated in Figs. 14 and 15. In this case the regulating member is arranged'in a tubular flange 92 projecting from the wall of the housing, in which flange it is displaceable axially. The iinger plate 45j is fixed to a tube 93 which extends through said iiange 92, and at the inner end of which the sleeve 38j supporting the cam disk 31j is displaceably mounted. "I'he iinger stop 42j is xed to the outer end ef a tube 94 arranged concentrically within the tube 93. The

spring 5| for rocking and pushing rthe regulating 30.

member and which is mounted in the space between the tubular flange 92 and the tube 93, is attached with one end to the outer end of the flange 92 and with the other end to the sleeve against which abuts a corresponding shoulder.

96 on the inner end of the tube 94. In order to prevent the finger stop 42f from partaking in the rotary movement of the finger plate 45f the tube 94 supporting the finger stop is guided at its inner end by a stud 91 fixed to the cover of the housing I0, which stud is provided with a longitudinal groove 98 into which extends a projection von the inner side of the tube 94. It is obvious that the'cam disk 3U, the tube 93 with the finger plate 45j and the tube 94 with the finger stop 42f may be moved uniformly as a unity from the extreme outer position shown in Fig. 14 towards the interior of the housing. IfV kthe cam disk would have been securely xed to the tube 93, that tumbler, against which the cam disk at that particulark moment abuts in axial direction, may easily be damaged by shocks on the iinger plate andthe iinger stop. In order to reduce the effect of such shocks, a shock absorb- Y ing spring |00 is inserted between the inner flange 95 of the cam disk and an inner shoulder |0| on `the tube Y93, the cam disk 31,1 together with its sleeve 38jy being axially displaceable in relation to the tubes 93 and 94. In order that` the inner end of the tube 93 may goV past the inner flange 95 of the cam disk 31j, the tube is cut away at two places, so that two longitudinal portions |02 and |03 only remain in diametrically opposite relation, and for these portions corresponding slots or recesses are arranged in the flange 95 of the cam disk (see the detail in Fig. 15). If the operating part of the regulating member is pushed inwards from the position shown in Fig. 14 with full lines to the position shown with dotted lines, and if the cam disk 31j is prevented from moving axially by any of the tumblers, the portions |02 and |03 on the inner end of the tube 93 will move through said open- @maar the regulating member for the tumblers has also served as the handle for operating the bolt of the lock. In certain cases it may be preferable to arrange a separate handle by means of which the lock and the door may be opened upon the tumblers having been set into the correct position by means of the regulating member. It is then necessary to make the handle independent of the tumblers, so that it is impossible during the setting of the tuniblers by feeling with the Yhandle to gather when a tumbler is set into the correct position. The handle shall, expressed in another way, not be able to actuate the tumblers during the setting of the latter and further it shall actuate the locking bolt only after all 4the tumblers have been set. For this purpose in a preferable form of embodiment of the invention there is a motion transporting device between the handle and the regulating member, which device couples together the handle and the regulating member, after the latterv upon the setting of the tumblers has reached operative position in relation to the lock bolt. This embodiment of the invention is shown in Figs. 16 and 17 which also give an example of a central restoring device for the part of the regulating member which actuates the tumblers, the said restoring device being intended to replace the laterally projecting pin 50 in the embodiment shown in Figs. 1 6.

In the embodiment shown in Figs. 16 and 17 the shaft |013` of the handle is rotatably mounted at its inner end by means of a journal |01 in a recess |08 in the wall of the casing I0. By means of a washer |09 fixed to the door 6| the handle is kept in position axially. At the inner end the shaft |06 has fixed thereto a radially projecting larm HEI which engages the fork-shaped end of a rocking arm H2 mounted by means of a pivot on the wall of the housing, the other end of said rocking arm extending between a pair of projections i i3, I4 provided with rounded working edges an-d arranged on one end of a lever I l5 which is pivoted on the tube 35g fixed to the wall of the casing and serving as a guide for the regulating member. The other end of the lever H5 is provided with a projection H6 extending towards the interior of the casing and adapted to cooperate with a corresponding recess ||1 in the cam disk 31 of the regulating member. In order that the cam disk may be set in correct position axially in relation to the lock bolt, the lever i5 is set back in a recess in the wall of the casing. A washer H8 separates the lever from the inner wall of this recess. A spring ||9 which actuates the arm ||0 formed on the shaft |06 of the handle, tends to press the opposite side of the arm against a sto-p pin |20, whereby the handle and the parts affected thereby are kept in a certain denite position.

For the purpose of restoring the cam disk upon the tumblers having been set, va restoring rod |2| is mounted axially displaceably in the stationary tube 35g. At the inner end this rod is provided with a shoulder |22 which projects through a longitudinal slot |23 in the tube 35g and extends further somewhat beyond the inside of the cam disk. At the outer end the rod |2| is provided with a knob |24 which serves as an operating han-dle. When drawing out the rod by means of the knob |24, the shoulder |22 moves in longitudinal direction of the' slot |23 and thereby carries along the cam disk. A slot |25 in the tube 35g' branching olf the slot |23 permits the rocking of the rod a certain angle, when the same has been drawn out to its extreme position, when the shoulder moves into the branch slot |25, so that the restoring rod and thereby also the cam disk are locked in the extreme outer position. The cam disk 31 is fixed as before to an axially displaceable tube 39g which with a certain space surrounds the stationary tube 35g. In this space is arranged the spring of the regulating member. One end of the spring is fixed to the interior of the axially -displaceable tube 39g and the other end is xed to the stationary tube 35g. rIhe iinger plate 45g having recesses serving as grasping means 46g is formed with a substantially spherical part |26 extending backwardly from the outer periphery, which part at the back passes over into a tubular flange or stud |21 surrounding the outer end of the tube 39g, in which stud the tube may move axially. In order to be able to carry along the tube 30g when the nger plate is rocked this latter is provided with a pin 220 screwed into thestud I2? which pin extends into a longitudinal slot |29 in the tube 39g. The ringer plate |26 is prevented from moving on the tube 35g, by means of the finger stop 2g iixed to the outer end of the latter. When the cam disk and the tube 39g supporting the same move axin ally outwardly from the position shown in Fig. 17 against the action of the spring, the outer end of the tube 39g is moved into the hollowness of the spherical part |26 of the finger plate.

rIhe mode of operation of the embodiment just described is as follows: 1f it is supposed that all tumblers are set into the correct positi-on and when the cam disk has just set the last tumbler, it is move-d backwards to its initial angular position in which the recess ||1 in the cam disk lies opposite to the projection H on the lever H5, so that the cam disk may move axially and the projection `||6 will engage with the recess ||1.'

Now the cam disk is in engagement with its radial edge with the projection 54 carrying along the lock bolt. When now the handle |05 is rocked in clockwise direction, the arm l0 will move the rock arm |12 in counter-clockwise direction, so that the lever 5 and thus also the cam disk are moved in clock-wise direction according to Fig. 16 and the bolt is moved out of locking position. It is to be observed that any such possibility to open the lock by means of the handle in the manner just described will not exist, until the projection H6 will engage the recess ||1 of the cam disk, for before this occurs, the movement of the han-dle cannot be transported to the lock bolt, in that this movement may only be transmitted by the cam disk. In order to restore the cam disk to its axial initial position, it is only necessary to draw out the button |24, so that it occupies its outer position, as shown with dotted lines in Fig. 17.

It is obviousthat the lock according to this embodiment may also be provided with shoot-bolts operable from the insi-de or the outside of the door in order to lock the lock bolt in locked or unlocked position. For the sake of simplicity such shoot-bolts have not been shown in Figs. 16 and 17, because their construction is disclosed in previous figures and it is clear to the professional man in which Way they should be applied to the embodiment just described.

In the embodiments of the invention hitherto described the regulating member is kept inoperative position for the various tumblers by means of a stop arranged on the regulating member, which stops abuts the tumbler to be set. The tumblers lthemselves thus serve as stop members for the axial movement of the regulating member. It is, however, possible to arrange separate stop members which independently of the tumblers successively stop the regulating member in the various positions and which afterwards are moved out of stopping position as the regulating member is moved in axial direction. An example of such a device is shown in Figs. 18 and 19, in which such parts of the regulating member are shown which areV necessary to understand the construction of the device, in that the rest of the lock may be executed in some of the ways illustrated in the embodiments hitherto described.

The finger plate 45h is also in this case formed with a hollow part |25 which accommodates the outer end` of the axially settable tube 39h. The nger plate 45h is prevented from moving axially outwardly by means of the finger stop 42h fixed to the stationary screw 43h and is prevented from moving inwardly by means of a shoulder |30 on a cylindrical sleeve 3| which ismounted concentrically relativeto the screw 43h and the tube 39h and is attached to the outside ofthe door 6|. In order to carry along the tube 39h in its rotary movement the finger disk is provided with a pin |32 extending into the hollow, which pin passes through a radial fiange |33 arranged on a cylindrical extension |34 on the outer end of the tube 39h. The pin 32 is displaceably mounted in the fingerplate and is provided, at that end which projects from the nger plate, with a knob |4I, and at its inner end with a radial circular fiange |42 to cooperate with a projection |43 on the extension 34. On a shaft |35 fixed in the cylindrical sleeve |3| are loosely mounted a num- -ber of stop pawls |36 each of which is kept by a spring |37 pressed against the outside of the tube 39h. The number of stop pawls corresponds to the number of positions in which the regulating member is stopped. Each stop pawl is provided with a rounded shoulder |38l to cooperate with the tube 39h or the extension |34 of the latter. The tube 33h passes into the extension |34 by means of a'radial shoulder |39. This latter extends around the circumference of the tube 39h and is at a certain place of the circumference provided with an axial recess |40, the .axial depth of which is equal to half the thickness of a stop pawl. In the position shown yon the drawing the first or outermost stop pawl |36 engages by means of its rounded shoulder |38 the recess |40 and the stop pawl lies with half its thickness externally of and with the other half internally of the shoulder |39.

When at the setting of the tumbler in the lock the finger plate 45h is rocked, the first stop pawl |36 which hitherto has prevented the regulating member from moving axially,glides upwardly over the rounded edges of the recess |40 and on the cylindrical outer surface of the extension |34.

when the regulating member can move axiallythrough the iniuence of its spring 5ML until the shoulder |39 abuts the next following stop pawl |36 which at its engaging end is kept pressed against the outer surface of the tube 39h and thus in locking position. The regulating member then moves axially a distance which is equal to'half the thickness of the stop pawl. When the finger plate after said forward rotation is released and when through the influence of its spring 5|h it has returned to its initial angular position,` the recess |40 `will register with the shoulder |38 on the next following stop pawl, and therefore the regulating member can move further a distance in axial direction, that is to say a distance equal to the axial length of the recess |40 or equal to half the thickness of the stop pawl. At repeated rotary movement of thenger plate the same cycle is repeated, until theregulating member with its shoulder |39 touches the bottom of the casing |3|, when all stop pawls will have been moved up to the cylindrical outer surface of the extension |34.

For the purpose of restoring the regulating member to its .axial initial position the carrying rod |32 is drawn out by means of the knob |4|, the radial flange |42 then abutting the projection |43 on the extension |34 and carrying alongthe axially movable part of the regulating member.

Instead of arranging the regulating member so that it must be rotated for the purpose of setting the tumblers, it may be arranged to have rectilinear movement for the same purpose, the part of the regulating member which cooperates with tumblers will then be given a corresponding form. If this part has a rectilinear movement in the plane of the tumblers, it may preferably be formed with an inclined plane which is moved into engagement with the tumblers and on which the latter glide during setting. Such an arrangement which also falls under the scope of the present invention in its broadest aspect is exemplied in Figs. 21 and 23 of the drawings. In the embodiment shown the regulating member consists of a wedge to be set by means of a shaft |44. The shaft |44 which is parallel with the shaft I6 of the tumblers 26 is guided at both its ends in straight-lined guides in the opposite walls of the housing l0, so that it may be displaced parallel with itself and with the bottom of the housing on which the underneath side of the wedge |45 rests. The wedge |45 is displaceably mounted on the shaft |44, so that it may move in the longitudinal direction ofthe latter. One end of the shaft |44 projects through a slot |46 inthe wall of the housing and at this projecting end it is provided with a handle |41, by means of which the shaft |44 with the wedge |45 may be moved in the longitudinal direction of the slot for the purpose of setting the tumblers. The handle is provided with a pointer |48 which glides over a numbered scale indicating the setting positions 0-9 of the tumbler. A rectangular member |49 fixed to the shaft |44 extends partly into the guiding groove |50 on the interior of the wall of the housing and serves to guide the shaft during its displacement along the slot |46. A similar' guiding device may be arranged at the opposite wall for the other end of the shaft |44. On that side of the member |49 which is turned towards the interior of the housing rests one end of a pressure spring |5|, the other end of which rests on the opposing side of the wedge |45 and thus tends to move the wedge in longitudinal direction of the shaft |44. The pressure spring |5| may if necessary be surrounded by a tube |52 fixed to the wedge and serving as guide. At its point the wedge is provided with a projecting stop |53 intended to stop, in the same way as the stop member 52 on the cam disk described above, the wedge in operative position for setting the respective tumbler. For the purpose of restoring the wedge to its axial initial position, upon all tumblers having been set, a restoring rod |54 may in analogy with the preceding embodiment be actuated by means of a button |55 and may be arranged centrally in the shaft |44 which for thisY purpose is made hollow. A shoulder |55 on the inner end of the restoring rod |54 extends through a longitudinal slot |51 and through the hollow shaft |44 tocooperate With the inner surface of the Wedge. At its back end the wedge is provided with a projecting shoulder |58 to cooperate with a corresponding shoulder |59 on the lock bolt I2.

It is obvious that the tumblers may in the same manner as described in connection with preceding embodiments be actuated by pawls which retain the same in the set position and that shoot-bolts and other details may be arranged in the same way asshown in preceding figures.

The mode of operation of the device just described is substantially the same as that described in connection with the embodiment shown in Figs. 1-6. The regulating member is shown in Fig. 22 in its `initial position, in which the wedge is kept in operative position for the purpose of setting the rst tumbler by means of the projection |53. If the tumblers for instance are executed to be set to respond to the combination number 503,915 the lock is opened in the following manner: The regulating member at rst is moved by means of the handle |4'| in longitudinal direction of the slot |46 until the pointer |48 registers with the number 5 on the scale. The lower corner of the first tumbler then glides along the upper surface of the wedge |45, and as this latter inclines in relation to the direction of movement of the wedge, the tumbler will be rocked about its shaft an angle corresponding to the length ofV said displacement, that is to say until the recess 58 will be opposite to the projection |8 on the bolt l2. The inclination of the upper surface of the wedge and the position of the recess 58 on the tumbler are of course so arranged that this will take place. When during this setting movement the wedge has been displaced to such an extent in relation to the tumbler that the shoulder |53 freely passes the lower corner of the tumbler, the wedge is moved a distance axially by the influence of the spring |5|, until its front surface will rest on the next tumbler and be stopped by this latter. When the shaft |44 Vthereupon is manually returned from the position 5 to' its initial position in the slot |46, the upper edge of the wedge will at the end of the movement pass freely the lower corner of the second tumbler and then the Wedge is forced by the spring |5| to move axially into operative position in relation to this tumbler, in which position it is stopped as before by the shoulder |53. The next number 0 is to be taken in a similar manner and the same process will be repeated at the following tumbler as described in connection with the first and second tumbler. After all tumblers have been set in position the wedge is forced to a position below the bolt so that the projecting shoulder is able to engage the shoulder |59 on the bolt which may now be brought in its unlocking position by moving the Wedge at the right as seen in Fig. 21.
